Remove unsightly bacterial growth in the aquarium?

Hi, for the past few weeks there's been a very large white bacteria colony growing in the gravel in my aquarium. Normally it's a good thing to have so many nitrite-degrading helpers. But the white coating stands out extremely strongly against the black, fine gravel, which I don't like so much. The only thing that bothers me is what's growing on the gravel, which you can see straight away. I don't really care about the good bacteria that are happening in the gravel that I can't see. Is there a good way to get rid of them? I've heard that these local bacteria colonies disappear on their own once there are no more nutrients to be found where they've settled. So the best thing to do is just wait and see what happens.

Besides, there are surely some invertebrates that would enjoy such a feast, right? Which ones? Snails are doing well in there, but unfortunately, all of my shrimp died within just two days due to a sudden outbreak of disease a few months ago. Since then, however, this bacterial growth seems to have flourished in some places on and in the gravel.

My aquarium's water parameters are now very stable, and all the inhabitants are doing great. I've also added a few thorny-eyed fish, which can often be seen during the day digging among the extremely well-growing plants or in the little sludge I have in there. My guppies are already heavily pregnant again, and the young guppies from the first two births are all healthy, too.

Thank you for any tips and suggestions!

Thorn eyes are kept on sand.

And leave the bacteria. Better not use fish until you see them. They’re here because the balance is missing. This must first form

However, thorn eyes can also be kept on mulm, clay, and other fine soft substrate, which they can stir through.

Anyway, you mentioned gravel

Wasn’t that clear from my text?

It was.

has long since been out of the inflow phase

Apparently not how the bacteria betray. The death of your shrimps is also a thing.
